The marine's thick, muscular thighs tense as he works his cock, the head of it disappearing between his lips as he sucks himself, tasting the pre-cum that beads at the tip. He spits on his hand, lubricating his strokes, his ass cheeks clenching as he fucks his fist. The soldier's breath hitches, his body tenses, and with a final, guttural groan, he comes, thick ropes of cum shooting onto his abs, marking his tan skin with his release.
